JAMES F. PLATT, OF STERLING, ILLINOIS.

HAY-LOADER.

SPECIFICATION forming part of Letters Patent No. 526,537, dated September 25, 1894.

A plication filed July 18,1894. flerlalllo. 517,899. (No model.) I

" zen of the United States, residing at Sterling,

in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements in Hay-Loaders; and I do doclare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention has reference to certain improvements in that class of hay loaders in which a series of rakes, operating in parallel lines, and provided with engaging projections on the lower surface of the rake bars or handles, are utilized to continuously and successively advance the hay up an incline, carried on two wheels and attached to the rear of the hay wagon.

In the class of hay loaders referred to, the hay engaging and elevating rakes have necessarily two movements-one in a vertical plane, and one in the line of the platform over which they are suspended. The former movement is attained byjournaling the rake bars respectively at the angles or elbows of the rotating, zigzag or crank shaft. This attachment imparts to the rake the necessary rise and fall, and a degree of reciprocal movement; but not a sufficient length of the latter. The added reciprocal or longitudinal movement of the rake bars essential to force the hay up the incline aforesaid, must be obtained, if at all, by mechanism outside of, and supplemental to the operation of the aforesaid crank shaft. This has been sought to be accomplished heretofore in various modes, but inasmuch as the rake bars, while journaled on the aforesaid crank shaft, must have a longitudinal play in excess of the diameter of the orbital movement of said attachment, and the rake proper during the interval of its inward movement must be held uniformly I to the surface of the ground, this supplemental movement of the rake and its bar has been difficult of satisfactory attainment.

ner to this department of the species of loaders referred to, and consists, first, in attaching the rake bars to the rear end of a short bar, carried on the aforesaid crank shaft by a flexible or toggle connection and to the front of said short bar by a sleeve attachment whereby the relation of the rake bar to said short bar, and therefore to the crank shaft, can be predetermined and regulated at each and every point of its round movement; second,in a supplemental independent shaft hav ing the sole function of imparting to the rake bar the necessary supplemental reciprocal movement before mentioned.

.As my invention pertains to only one part of the aforesaid loader, and the residue of the latter is well known, I do not deem it necessary to show or describe the entire structure, but will confine the description herein to the parts embodying my invention, and such adjunctive parts as may be necessary to illustrate the construction, location, and operation of my invention. In the drawings, Figure l is a perspective of a portion of a hay loader embodying my invention. Fig. 2 is a detail of the arm carried on the aforesaid crank shaft and my method of attaching the rake bar thereto. Fig. 3 is a detail of a portion of the mechanism employed in giving the aforesaid additional sweep to the rake and rake bars.

Similar letters and figures refer to similar parts throughout the several views.

each side of the machine, the description of one side will suffice for both.

Referring to Fig. 2, G is a short arm placed above the usual rake bar H and in the vertical plane thereof. The arm G is pivotally attached to the crank shaft 0, at the elbow or IOO ure of theaecumu'lated hay-under theupper portien of the rake bars H,and'expetli ye theI and inelosingvplape said 'sl'ightly longer' than the 1 permits'elimited upward a ang1e ef the latter-5 5165111 5 loosely seated on saidshaftaudboltedatq t'he e v lqwe portion uf ther keib hzflg to the upper surfaee offthemke barHJWithin Q a 'shortdis taneeiof thel'loeation of theflmke L, and hingedat its-uppe f-61 1 tdtheP-lbweti orrear end of thea jrm G.
